Original'applcaton led May 15, 1922, Serial 110.561,132, now Eatent No. 1,493,961, dated May 13, 1924.

Divided and this application filed This application is a division ot my prior copending application, Serial No. 561,132, filed May 15, 1922, (upon which application Patent No. 1,493,961 was granted May 13, 19241) and is designed tor use i-n connection with the type ot 1ailway car trucks described in said copending application and in my United States Patent No. 1,457,345granted lune 5, 1923. The invention claimed here in relates more particularly to the bolster construction and the construction immediately related thereto.

Figure 1 is a longitudinal sectional view oit the end et a built-up bolster constructed 'to cooperate with and torni part ot my improved truck construction.

Figures 2 and i are sectional views on lines 2 2 and 8MS ot Figure 1.

Figires Ll and 5 are side elevations of the end and central part, respectively, ot a bolster oit the type known as the Simplex, but embodying new features adapting it to my invention. y

Figure 6 is a view trom beneath of the structure shown in Figure il.

'Figure 7 is an end view of the bolster shown in Figures t, 5 and G.

Figures 8, 9 and 10 are respectively a plan, side elevation and end view of the end part of a pressed steel bolster similar in general construction, but embodying an end `asting ot different form.

The bolster shown in Figures 1, 2 and 3 while con'tmming generally to the type of bolster heretofore in. common use and known as the Simplex bolster differs therefrom in the substitution ot a channel 105 for the plate used in this part of the Simplex construction, aud also (litters n the form of the end casting or spring seat member, which latter part in my irnpii'oved construction is designed to co-opcrate with an assemblage ot springs consisting of a central group supported at a lower level than the outer or en d springs as set forth in my co-pending application and patent above referred to. The elevation oil the outer or end springs is clearly indicated in Figure 2 and other views and one mode of disposing the springs horizontally is indicated in dotted lines in Figure 6, the tour central springs there shown being supported at a lower level than the outer or end springs. I have substituted the. channel. 105 for the plate member here- April 23, 1924. Serial No. 708,360.

totore used in order to increase the transverse strength of the bolster. As shown in Figures 1, 2 and 3, the side -flanges 107 ot i truck as tally set forth in my patent and copending application above referred to,but independently oi' the width of the spring assemblage the end casting is ot novel form in order to accommodate springs disposed at different levels, such disposition ol' the springs having advantage regardless ot the total width ot the assemblage. Vlrhe bottom wall ot the end casting` shown in Figures 1, 2 and 3, has a central part, 1, on a lower level than the end parts, 2,the. end sections being connected to the central section by the vertical wall sections, 1. The vertical side walls, 5, are spaced apart just sufficiently to receive between them the. 'downwardly extending side flanges, G, of the channel 109 which terms the compression member o'l' the bolster. In order to accommodate a wide spring assemblage the projections 111 are provided, each ot these projections having two vertical walls 7 projecting from `the wall 5 and joined at their outer extremities by the wall 8 parallel to the wall 5. rlhe box-like projection so formed is closed at the bottom, as indicated at 9 by an extension of the elevated part 2 of the bottom wall of the casting. The projections 111 are ot less extent longitudinally ot the bolster than the central part of the casting 'for the reason that the particular casting illustrated is dcsigned for a spring assemblage such as illustrated in Figure (l where single end springs 10 obviate the necessity oi making the projections 111 of the.y full width oi the end casting. Extending upward from the part 1 of the bottom wall are two vertical webs 3, 3, which with the rear wall 12 support the inclined top plate 11 which underlies the lower or tension member of the bol ster and is riveted thereto. Thebolster tension member 105 is at its end folded over the end of the bolster compression member 109, there being a iller plate 13 interposed between these members and rivets passing through both the tension and compression members and filler plate as shown. The structure shown in Figures 1-, 5, G and 7 is oi.E a torni in common use and known as the Simplex bolster. ln these views show the method Commonly used heretofore for joining the tension and Compression members and end casting in place of my improved means illustrated in Figures 1 to 3. The form of the spring seat on the under side of the casting, the projections 111 and the relations of these part-s to each other are similar to the structure shown in Figures 1 to 3. The bottom and side walls of the end Casting shown in Figures l to 7 are secured by rivets 112 to the tension member 107 (Fig. et), and to the downwardly directed side flanges 150 of the compression men'iber, (which latter is designated generally by the numeral 1.51) as shown in Figures il, 6 and 7.

In the construction shown in Figures 8, 9 and 10 the bolster shown comprises a lower longitudinal member o1 U-shape cross seetion, as shown most clearly in Fig. 10, and with out-turned flanges 153 at the upper edges oit the side walls. This lower longitudinal member is ot' greater depth at the center as indicated by the downwardly inclining bottom wall 155 (Fig. 9) thereby better resisting the tension stresses, and the upper plate 154 which is riveted to the out-turned lianges 153, forms a compression member. The end casting shown in Figures 11 to 13 takes the form of a box which slips over the end of the bolster, and the projecting sides 121 of the end casting are of less vertical depth than the bolster and the central part of the Casting, thereby providing higher seats beneath the bolster for the end springs than for the Central group of springs. As clearly appears in Figure 11, the side walls of the bolster 122 are brought closer together at 124 at the end of the bolster in order to afford clearance for the end springs 1.13.

I claim:

1.. In a railway ear truck, a bolster comprising a longitudinal section having a spring seat at each end, each of said spring seats being of greater width than the interw mediate longitudinal part oit' the bolster and projecting transversely thereof, the Central art of each of said spring seats being at a ower level than the transversely projecting end parts.

2. In a railway truck, a bolster compris-- ing separate compression, tension and spring seat members, each of said spring seat members being of greater width than said tension and compression members and forming a spring seat the end parts oi.' which project transversely of the bolster beyond said compression and tension members, the eentral part ol said spring seat being at a lower level than the end parts, springs oo-aeting with said spring seat, and means for attaching said Compression, tension and spring seat members together.

3. In a railway ear truck, a bolster comprising separate compression, tension and spring seat members, each of said spring seat members being provided with means for engaging springs supported with their upper ends at dilferent levels, and means for attaching said eon'ipression, tension and spring seat members together.

1l. In a railway ear truck, a bolster comprising` separate upper and lower longitudinal members and spring seat members at the opposite ends thereof, eaeh of said spring seat members being provided with means for engaging springs supported with their upper ends at different levels, and means tor attaching said upper, lower and spring seat members together.

Signed at Lima, Ohio, this 19th day of April, 1924.
